- Data visualization techniques for real-time information — A custom and dynamic dashboard for analyzing surveys' resultsPublication . Toasa, Renato; Maximiano, Marisa; Reis, Catarina I.; Guevara, DavidTo achieve the most understandable and accurate display of information, a study on the available techniques of data visualization for real-time information must be made. Customizing existing platforms and designing specific boards, are among the important task to perform an accurate visualization of the information. In this paper, we conduct a literature review of data visualization, its techniques and existing dashboard platforms. We implemented a generic and dynamic dashboard based on real-time information with the aim to assess the impact of the available Data Visualization Techniques in the developed dashboard. Therefore, our Dashboard users will be able to interact with the information, based on an initial set of hints, charts, tables and reports, produced by the Dashboard itself. This will allow us to test an existing set of data visualization techniques and create a new tailored dashboard, showing that dashboards can become a unique and powerful means to provide information
- Energy consumption behaviour characterization with mobile gamificationPublication . Toasa, Renato; Silva, Carlos; Silva, Catarina; Gonçalves, Dulce; Neves, Luis; Marcelino, LuisExcessive electric energy consumption results in high costs for consumers, and often on using non-renewable resources. Additionally, in many cases, it is difficult for the consumer or for the energy provider to determine if one or more equipment is being used efficiently. Therefore, the main objective of this work is to promote awareness about energy consumption. For that purpose, a mobile application with a gamification approach was designed to identify users’ behaviors towards the use of energy and, based on the user’s answers, offer advices to save energy and promote ecological awareness. The outcome of using gamification on a mobile application with such goals results in a streamlined data collection application that combines information and entertainment. The collected information is being gathered to potentially create consumer profiles that better reflect the user’s energy consumption.
- Kinect sensor performance for Windows V2 through graphical processingPublication . Vargas, Javier; Mariño, Christian; Aldas, Clay; Morales, Luis; Toasa, RenatoThe present paper describes a study based on the loss and gain of frames that are obtained through sensors (color, depth, and body tracking) of Kinect V2. For this purpose, it is established a time to obtain each frames per second (FPS), evaluating a performance of sensors in three evaluation instances, using native Kinect V2 libraries and other graphic processing libraries. In addition, several experimental tests were carried out, in order to verify the best performance of a test application based on graphical processing of each sensor.
- Performance Evaluation of NoSQL and SQL Queries in Response Time for the E-governmentPublication . Flores, Ana; Ramirez, Stalin; Toasa, Renato; Vargas, Javier; Urvina-Barrionuevo, Renato; Jose M. LavinSociety demands accurate, right, quickly and easy access information. Therefore, governments are forced to implements or improve information systems with modern technologies. This research work is focused on the research of responses times on relational and non-relational data base models in an experimental data base system provided by the Función Judicial del Ecuador. The data is migrated for load in NoSQL allotment, and the performance tests is obtained a document-oriented data model. With these tests we could know the best database, focusing all on response time of data queries that have been used on performance tests. In addition, we evaluate the performance before and after the relational database administration system (RDBMS), obtaining as a result that the first test of the queries made to MongoDB substantially surpass the queries made to SQL Server, but in the subsequent tests the times they tend to be similar.
